Symptomatic lobar intracerebral hemorrhage during extended lecanemab treatment: A case report.
Article in Journal of Alzheimer's disease reports. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Lecanemab is an anti-amyloid-β protofibril antibody that slows cognitive decline in early Alzheimer's disease. Although amyloid-related imaging abnormalities (ARIA) occur predominantly early in treatment, reports of hemorrhagic events during extended treatment beyond 18 months remain limited. A 77-year-old woman completed a standard 1.5-year lecanemab regimen without ARIA on surveillance MRIs. The day after her 42nd infusion, she acutely developed confusion and incomprehensible speech. MRI revealed a 2.5-cm left parietal subcortical hemorrhage. This case highlights that symptomatic lobar hemorrhage may occur even during extended lecanemab therapy, underscoring the importance of continued safety monitoring during extended treatment.
